Advanced research in SWIR imaging

High-resolution and cooled Xeva-1.7-640 for excellent image quality research

In one compact housing, the Xeva-1.7-640 digital camera combines a thermo-electrically cooled InGaAs detector head and the control and communication electronics.

The Xeva-1.7-640 unit is available with standard (up to 1,7 μm) InGaAs detector arrays and comes in various speed versions: 25 Hz and 90 Hz. It allows you to choose the most suitable detector camera configuration for your specific application. The camera head interfaces to a PC via standard USB 2.0 and CameraLink. Each camera is delivered with a graphical user interface, Xeneth, which offers direct access to various camera settings such as exposure time and operating temperature. The camera outputs 14 bit data. The software tools include two point uniformity correction and bad pixel replacement.

Benefits & features

  • High dynamic range
    A lot of detail between the brightest and darkest parts of an image
  • Stand alone operation
    Camera can be connected to a screen directly (via analog out), no need for a PC to control the camera
  • High definition images
    640 x 512 Pixels for high image quality
  • Performance optimization
    Easy and continuous access to control parameters such as integration time and frame rate
  • TrueNUC image correction
    Image correction valid for a range of integration times
  • Thermal imaging of hot objects
    SWIR cameras are ideal for thermal imaging of hot metals (> 300 degC)
  • Flexible programming in an open architecture
    SDK (Software Developing Kit) available for all cameras - samples available for C++, LabView, Linux…

Designed for use in

  • Art inspection
    SWIR photons can penetrate through paint, hence underdrawings can be investigated
  • R&D (SWIR range)
    SWIR range is a relatively unexplored range and hence providing much research opportunities
  • Hyperspectral imaging
    Combination of spectral imaging and 2D imaging. Our SWIR camera are used for hyperspectral SWIR imaging
  • Thermal imaging of hot objects (in the 300˚ C - 1200˚ C range)
    SWIR cameras can be used for thermal imaging in the temperature range above 300degC
